Advertisement Posted May 18, 2007 Posted May 18, 2007 Hi usm, Take a look here Once again: Leica IR E39 filter + o-ring mont on CV15mm. I'm sure you'll find what you were looking for!
tashley Posted May 18, 2007 Share #2 Posted May 18, 2007 Don't use an O ring, use sellotape. One really long strip, cut with a scalpel to about 1.5 mm wide and then wrapped two or three times around the perimeter for the filter, and it will stay in place beautifully... quick and easy and highly effective...

markjames Posted May 18, 2007 Share #3 Posted May 18, 2007 I agree, I loved that post showing the o-ring and while I'm pretty handy mechanically and have amassed a beautiful collection of o rings just waiting for my Leica filter to show, I'll be damned if I could get the filter down on the CV15 with the o-ring on it. After smudging the filter repeatedly I walked over to my art bin, grabbed some black photo tape (looks like black masking tape only a little thicker), wrapped a thin strip (cut with an x-acto knife) around the filter edge and nudged it on in. I really wanted the o-ring to work -- clean, Leica-like solution and all that, but the tape works better and you can custom fit depending on how much tape you use.

argomazov Posted May 18, 2007 Share #4 Posted May 18, 2007 Hi!I just got an o-ring from Luca an I have a really hard time to squezze the E39 filter with the o-ring mounted on the CV15mm? Any suggestions or tips? Thanks Mario Mario, I finally managed to fit mine yesterday evening. I think I had to try around 10 times, divided between three evenings, before making it: the folks who said it was a tight fit really love euphemisms :-) Anyway, the only suggestions I have is to arm yourself with a LOT of patience, and use your fingernails to keep the O-ring from bulging. Good luck, Luca Link to post Share on other sites More sharing options...
george + Posted May 18, 2007 Share #5 Posted May 18, 2007 Mark, excellent suggestion. I did it too, reasonable easy. But to make it really easy, I screwed two old UV filters to the IR/UV filter. One on top, one on bottom. Then I applied the tape which went on much simpler usig the wider surface of three filters. Then I trimmed along the filter dividing lines - having left just a bit of space between the filters for the knife edge. Then I took of the bottom filter, pushed in the two remaining ones - with the IR/UV filter closer to the lens - in reverse of course, or it touches the lens. Then I removed the remaining old UV filter from the outside and trimmed along the sunshade to fully hide the tape. Looks neat and seems() solid. Many thanks for all the experimentation and the fine suggestions. Link to post Share on other sites More sharing options...
Woody Campbell Posted May 18, 2007 Share #6 Posted May 18, 2007 Or put a two little patches of the fuzzy side of Velco on the outside of the filter mount 180 degrees apart. Works really well. Link to post Share on other sites More sharing options...
usm Posted May 25, 2007 Author Share #7 Posted May 25, 2007 Advertisement (gone after registration) Is it possible to mount the IR filter from Leica in reverse order on the CV15mm lens? Are the two sides different? I tried really hard to mount it with the o-ring - no way. So I'm using tape, but the filter touches the front lens. Can I use the filter from the other side? Thanks Mario Link to post Share on other sites More sharing options...
george + Posted May 25, 2007 Share #8 Posted May 25, 2007 I mounted mine in reverse because - as you write - otherwise it touches the lens. Previous entries noted that it made no diffrenece but I made no tests. Good luck. Link to post Share on other sites More sharing options...
Stephen.s1 Posted July 3, 2007 Share #9 Posted July 3, 2007 If no one else has mentioned this, I'd like to say that the referenced lens/filter scheme will produce heavy vignetting when used with a full-frame, non-digital, Leica. I didn't bother to remove the filter when shooting two rolls of Tri-X. Forewarned is forearmed. Link to post Share on other sites More sharing options...
como Posted July 3, 2007 Share #10 Posted July 3, 2007 I took an old innertube from a bicycle, cut off a ring (from one tube you can make 500 rings) and stretched it around the filter. When you start with a ring from about 10 mm wide it is easy to handle. Afterwards you can cut off what is beside the filtermount. It fit perfect. Good luck, Co Link to post Share on other sites More sharing options...
ck1 Posted July 3, 2007 Share #11 Posted July 3, 2007 I second the velcro strips. I struggled with selotape and O rings, but the velcro is perfect - you can slip the filter on and off quite easily, which is ideal for panoramas. Link to post Share on other sites More sharing options...
hdrmd Posted July 3, 2007 Share #12 Posted July 3, 2007 I agree with the use of tape. I tried repeatedly to get the O ring to work. The tape worked the first time. Regards. DR Link to post Share on other sites More sharing options...
afineman Posted July 4, 2007 Share #13 Posted July 4, 2007 If anyone wants I have extra o rings. no charge. in order to get one i had to get a box of 10. afineman[at]gmail.com ps. I got the tape to work easier than the o rings. but now i have a ton of o rings. Link to post Share on other sites More sharing options...
wparsonsgisnet Posted July 5, 2007 Share #14 Posted July 5, 2007 I mounted mine in reverse because - as you write - otherwise it touches the lens. Previous entries noted that it made no diffrenece but I made no tests. Good luck. Owee! When I saw this post I realezed that the filter on my CV15 was touching the lens. For those of you who have not make this mistake -- it blurs all the pictures taken with the lens. I reversed the filter and the pix are once again, well, pix. I'm waiting for Milich's adapter.

sean_reid Posted July 5, 2007 Share #15 Posted July 5, 2007 Speaking of which...For those for whom the cost is in budget, I'd strongly recommend the Milich adapter over any kind of O-ring, tape, etc. solution. Its much more secure and, importantly, it shades the filter and lens. The solution we've been using with pressure fitting the filter in leaves it, essentially, unshaded and very vulnerable to flare. In other words, I think that the Milich solution makes our temporary approach obsolete so long as one has the money needed for the former. Cheers, Sean Link to post Share on other sites More sharing options...
wparsonsgisnet Posted July 5, 2007 Share #16 Posted July 5, 2007 I am waiting for my Milish adapter to be delivered, but Sean is definitely right about an unshaded lens. I get lots of flare from side and forward sources of oncoming light. Link to post Share on other sites More sharing options...

george + Posted July 5, 2007 Share #19 Posted July 5, 2007 You guys convinced me too. I just sent an order to John. This way the tiny cs15 will rest between two pieces made by John Milich. Link to post Share on other sites More sharing options...

George, you're right, we need a name for John's stuff: Millwich (for adapter and hood sandwich on either side of a CV lens), WATEhood, double intender (for a possible forthcoming double hot-shoe adapter, with pc connection) as in double entendre, Or perhaps a new adjective, like "JLM quality," to denote items manufacturd to a high standard. Or a new noun, "jlmagination," denoting far-seeing creativity of machined goods for photographers. Link to post Share on other sites More sharing options...
